Problem zeroing free blocks of /var/tmp/file

[zerocarbthirty]

Howdy, I'm using Lorax to create an alma9 liveimage that should be pxe bootable.

I know this gets complicated so I am trying to keep it very simple. Here is my command line:

livemedia-creator --live-rootfs-keep-size --make-pxe-live --image-name=file --ks newthing --iso=/isos/AlmaLinux-9.5-x86_64-minimal.iso

The entire installation process seems to complete inside of the KVM environment and then I just get this output:

I dug through all of the generated logs. The only thing I see is in the program.log:

I also noticed this in the livemedia.log:

2024-12-12 15:09:44,941 INFO pylorax: Disk Image install successful

It seems like the output in program.log is simply a symptom of whatever problem causes the rootfs.img file not to be actually created in: /var/tmp/lmc-work-vuoe831l/squashfs_root/LiveOS/rootfs.img but I cannot find any reason for why that file isn't created in any of the logs.

Does anyone know what I might be doing incorrectly? or have any suggestions. I am guessing that the image it's creating is invalid because of this line "2024-12-12 15:09:44,947 DEBUG pylorax.imgutils: Unable to mount anything from /var/tmp/file" but I have no idea why.

Is it because I am using this in my kickstart? "part / --fstype="xfs" --size=10000"?

I am trying to adapt this from an older setup that worked with CentOS 7.

thank you so much for any guidance.

I was actually able to get this to work with --no-virt in anaconda mode for the most part.

Oh, interesting. I'll try to look into this at some point, but I haven't actually used the PXE option in quite a while and time is currently short so it may be a while. If you have additional info in the meantime feel free to add it here.
